Problems solved by technology

However, the live working method is very dangerous, and the high-altitude electrified vehicle is easy to cause traffic jams on the congested urban roads.
The second is to use an aerial work vehicle to trim the branches that do not touch the live wires, but this method also requires the cooperation of a climbing vehicle, which is not only inconvenient to drive on the road, but also greatly reduces the working efficiency
Obviously, the above two methods can only work on solid and flat roads, and cannot meet the environmental requirements that vehicles cannot reach.

Embodiment 1

[0026] a kind of like Figure 1-3 The shown insulating pruning device includes an insulating tripod support frame 1 and an electric saw 2. The insulating tripod support frame includes three telescopic support rods 11, and the upper ends of the support rods are hinged together. The top of the top is provided with a pulley 12, and the bottom of one of the telescopic support rods is provided with a hand winch 13, and the insulating rope 14 of the hand winch is used to hang the insulating operating rod after bypassing the pulley on the top of the insulating tripod support frame; The insulating tripod support frame also includes an inverted tripod support frame, one end of the inverted tripod support frame is hinged together, and the hinged end stands upside down on the ground, and the three legs of the inverted tripod support frame support the insulating tripod support frame respectively. shelf. The bottom of the supporting foot of the inverted tripod support frame is provided wi...

Abstract

The invention discloses an insulative pruning device, which comprises an insulative three-leg support frame and an electric saw, wherein the electric saw is hung on the insulative three-leg support frame to prune tree branches. The insulative pruning device has the advantage that the branches near a power distribution network can be pruned by an operator standing on the ground (or standing on an auxiliary tool lower than 2m), so the effects of safety, light weight and high efficiency are realized.

Description

technical field [0001] The invention relates to a branch trimmer, in particular to an insulating trimmer. [0002] Background technique [0003] With the continuous improvement of people's living standards, the issue of urban greening has received great attention. A large number of tall trees have also been planted around the overhead lines of the 10kV distribution network, which frequently causes accidents where high-altitude trees touch live wires and cause line trips and power outages. [0004] To solve the problem that above-mentioned high-altitude trees touch live wires and cause line tripping, the main measures adopted at present are as follows: the one is to use electrified operation methods to prune the branches close to or touching the wires. But adopt live work method, risk is big, and high-altitude electrified vehicle is easy to cause traffic jam on the urban road of congested traffic. The second is to use aerial work vehicles to trim branches tha...
